conventional detector（non-coded）intelligent detector（coded） installation location: point type（distance between ceiling, roof, wall and height from the ground） line type（laying way, distance between the roof , installation spacing） distance between other equipment and beam plate

Under normal circumstances, the rain valve group of electromagnetic valve, stage fire screen and other important fire facilities should also be set up multi-line linkage. Note: “Fire Regulations” only require fire pumps and fire engines in addition to automatic control, the need for manual direct control.

Number of loops Combined with multi-line disc, the number of bus lines Controller capacity

3. multi-line disk, bus disk number calculation 1) multi-line disc Number of linkage points (fire pumps, fire blowers, rain valves, etc.) the point number of each multi-line disk Linkage point arrangement Number of multi-line discs 2）bus disk Number of linkage points (strong cut, emergency lighting, shutter doors, elevators, etc.) the point number of each bus-line disk Linkage point arrangement Number of bus-line discs

Note: fire regulation does not require the setting of a bus disk, but in order to facilitate the operation of some more important equipment (has been set to multi-line linkage point without repeating the bus point), many projects will design the bus, combined with the control module. Commonly need to set the bus linkage point of the equipment are: non-fire power cut, emergency lighting, rolling doors forced landing, elevator landing, bell, fire valve reset.
